Abstract:

Aim: The primary purpose of this part was to Kinematical variables analysis of the shot-put activity in Para-Athletics (Class F32/33) and their relationships with digital level achievement. Methods: International Paralympic athlete "Kerdjana Kamel" participated voluntarily in this study. He's the gold medalist and the record holder in this class F32/33 (Age: 37 years, Height: 1.76 m, Weight: 82 kg, Type of Impairment: cerebral palsy, the origin of impairment: congenital, club: GSP Alger, Best Digital level: 12.24 m). The analysis of the present study was done with the software Kinovea software 0.8.15 for the kinematical analysis, we used two cameras (AEE. 120ips, 1280*720, 720p) for the record the Kinematic performance during the first and second phase (Start and Finish Pushing) in the Shot-Put. sites of this cameras (Cam; X0.5m, Y1.5m. Cam; X6m, Y5.5m). Shot-Put tries were applied for our sample (the international Paralympic athlete) in eight tries, we choose the best six tries for analysis. The data were analyzed in SPSS program, descriptive statistics (mean±Sd, Std.E) and Pearson test for the correlations between variables. Results: As a result of the statistical analysis, there was a positive significant correlation of the Digital level with Distance of shot from the armrest (0.04*), and with The wrist Angle of the shooting hand (0.015*) in the first phase (start pushing), and in the second phase (finish pushing) there was a negative significant correlations of the Digital level with Pushing angle (-0.013*), and Positive significant correlations with Shot height (0.006**). Conclusion: Based on the kinetic Performance results analysis of Paralympic elite (the Shot-Put Activity, Class 32/33) in practice; we confirm: 1) The increase in the values of the variables of Distance shot from the armrest, and the wrist Angle of the shooting hand in the first phase of pushing (start) affect the digital level achievement, Also the Shot height variable in the second phase of pushing, 2) The decrease in the value of Pushing angle variable in the second phase of pushing (finish) affects the digital level achievement.
